The second race began with a red-flag interruption because of a crash between Crosslink Kiwi's Max Hewitt and IGY6's Hayden Bowlsbey, but when it restarted, Hedge was similarly dominant to take another win.
The qualifying session was rained off, meaning Hedge was awarded pole position by virtue of his standings lead.
He led Shehan all race long to take his fourth straight win, with Becklin third once again after he fended off Jensen's Oliver Westling at the start and the latter made a mistake.
Normal service returned for the second race, with Hedge starting fourth, but passed Westling, Becklin and Shehan in the first three turns to take the lead and the win.
A timely safety car brought him back right behind Shehan, and the latter then also made a mistake to restore the original order, before the race finished under caution.
Hedge looked set for another triple victory, before he was hit with an engine issue that forced him to retire from race three.
Becklin inherited first place, fighting off Shehan to take his first win of the season, while Bowlsbey secured his first podium with a late move on Westling.
Speed Factory's series returnee Cole Kleck took second at the start and fought with Shehan through the first half.
Race two saw Westling take his second win in a photo-finish after he passed polesitter and race-long leader Hedge through the final corner.
Most qualifying sessions only saw the top trio of drivers within a second of the pole position time, and the field was often spread far during the races.
With the attraction of a Super Formula scholarship also set to depart the series through the planned powertrain change, it is hard to see how interest in the championship could grow in the coming seasons.
